慢走絲工作原理

慢走絲工作(zuo)原理(li)：

       慢走絲(si)是(shi)利用連續移動的(de)細金屬絲(si)（稱為電(dian)極絲(si)，一(yi)般為銅絲(si)）作電(dian)極，對工(gong)(gong)件(jian)進(jin)行(xing)脈沖火花放(fang)電(dian)，產生6000度以上(shang)高溫，蝕除金屬、切割(ge)成工(gong)(gong)件(jian)的(de)一(yi)種數控加工(gong)(gong)機床。慢走絲(si)加工(gong)(gong)原理是(shi)在(zai)線電(dian)極與(yu)工(gong)(gong)件(jian)之間存(cun)在(zai)的(de)有縫間隙，持(chi)續放(fang)電(dian)去除金屬的(de)現象。

       由于慢走(zou)絲(si)線(xian)(xian)(xian)切(qie)(qie)(qie)割(ge)(ge)機(ji)(ji)(ji)是采取線(xian)(xian)(xian)電(dian)(dian)極(ji)(ji)連續供絲(si)的方式，即線(xian)(xian)(xian)電(dian)(dian)極(ji)(ji)在運動過程(cheng)中完成加工(gong)(gong)(gong)，因(yin)此即使線(xian)(xian)(xian)電(dian)(dian)極(ji)(ji)發生損(sun)耗，也(ye)能(neng)連續地予(yu)以(yi)補充，故能(neng)提高零(ling)件(jian)加工(gong)(gong)(gong)精度(du)。慢走(zou)絲(si)線(xian)(xian)(xian)切(qie)(qie)(qie)割(ge)(ge)機(ji)(ji)(ji)所加工(gong)(gong)(gong)的工(gong)(gong)(gong)件(jian)表(biao)面粗糙(cao)度(du)通常可達到(dao)Ra=0.8μm及以(yi)上，且慢走(zou)絲(si)線(xian)(xian)(xian)切(qie)(qie)(qie)割(ge)(ge)機(ji)(ji)(ji)的圓度(du)誤差(cha)、直線(xian)(xian)(xian)誤差(cha)和尺(chi)寸誤差(cha)都較快(kuai)走(zou)絲(si)線(xian)(xian)(xian)切(qie)(qie)(qie)割(ge)(ge)機(ji)(ji)(ji)好很多，所以(yi)在加工(gong)(gong)(gong)高精度(du)零(ling)件(jian)時，慢走(zou)絲(si)線(xian)(xian)(xian)切(qie)(qie)(qie)割(ge)(ge)機(ji)(ji)(ji)得到(dao)了(le)廣泛應用。除(chu)了(le)早期(qi)的中小型企(qi)業，在諸如航空，汽(qi)車，醫療等大型企(qi)業的加工(gong)(gong)(gong)工(gong)(gong)(gong)廠內(nei)也(ye)極(ji)(ji)為常見。
